One Laptop Per Child
Amazon is helping with the One Laptop Per Child program: Link
I saw Nicholas Negroponte, the founder of one laptop per child, in an interview last night. He said that his ultimate goal with this program, which will take a good 20 years to realize, is world peace.
I like his chances. I think it can work (and even wrote about it last year: link). I say the following with no exaggeration: If he pulls this off, Negroponte will go down in history as one of the greatest men who ever lived.
